A New Rechargeable Battery
A new rechargeable battery comes in a discharged condition and must be charged before use. Upon initial use the battery may require three to four charge/discharge cycles before achieving maximum capacity. It is normal for a battery to become warm to the touch during charging and discharging. Rechargeable batteries in portable lighting devices and two-way radios are principally made using Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH) or Lithium Ion. (Li-Ion) technologies, that is NiCad rechargeable battery, nimh rechargeable battery, and Li-Ion rechargeable battery. Rechargeable flashlight batteries are generally Nickel Cadmium. Each type of rechargeable battery type has unique properties.
How to Handle Rechargeable Battery?
If the battery will not be in use for a month or longer, it is recommended that it be removed from the charger and stored in a cool, dry, clean place. A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period. Actual battery run-time depends upon the power demands made by the equipment it powers. The total run-time of the battery is also heavily dependent upon the design of the equipment.
Here are some basic tips for battery handling:
Do not short-circuit. A short-circuit may cause severe damage to the battery or even explosion.
Avoid dropping or impacting rechargeable batteries. This could result in the exposure of the corrosive cell contents.
Avoid exposing the battery to moisture or rain. Most flashlights are sealed against such exposure.
Always make battery away from fire or other sources of extreme heat. Never incinerate. Exposure of battery to extreme heat may result in an explosion.
In US, many rechargeable batteries are produced in other countries (mostly China, China battery manufacturer).
Using Lifetime of Rechargeable Battery
The life of a rechargeable battery operating under normal conditions is generally between 500 to 800 charge-discharge cycles. This translates into about three years of battery life for the average user. As the rechargeable battery begins to die, the user will notice a decline in the running time of the battery. When a battery that originally operated the flashlight for a whole shift is only supplying the user with an hour's worth of use, it's time for a new one.
